You should be able to post shortly, try again later.
In the meantime, here is some info to help you organize your data and how to post it.

Fotomatt, the forum limits links until you have 4 posts. So try again. My signature links to articles that describe the organization of data charts, and method for linking from Imgur. You should be good to go on your next post. If not, just post the link with a space, and we can figure it out.

You beat me to it. What we need to see is the Daily Details chart. It looks like this:

Just a couple quick observations. Most of what I'm seeing here is mixed events that are most likely related to getting accustomed to CPAP therapy. These tend to go down in time. Your leak rate is higher than ideal, and that needs to be the first priority to avoid the sleep disruptions and discomfort related to air blowing in your eyes or face. Most of your events are concentrated near the beginning and end of therapy. That suggests you're not sleeping deeply, and may account for a lot of the clear airway and hypopnea events. For example on 11/17 you had a number of events until midnight, then a very quiet period until 3:00 AM. A period of disrupted sleep from 3:00-4:00, and another quiet period.
Since there really isn't much pattern for obstructive apnea here, a pressure increase is not warranted. If you are sensitive to the changing pressure, it might be helpful to narrow the pressure range by setting the minimum at 7.0, or even use CPAP at 9.0. I do think you should turn off the ramp which starts your pressure at 4.0. It's pretty clear that may be compromising your mask fit, and really causes a lot of unnecessary early events.
If you had a titration study, what was the recommended pressure?
